power steering on 2002 Toyota Camry

what would cause my power steering to seem like I don't have power steering? We replaced the serpentine belt and it seemed fine for a couple of days but now it is hard to turn again

Do you hear a squealing sound (may be sign of a loose serpentine belt) when operating the steering, or do you hear a gurgling sound (low fluid in the reservoir).
Check for leakage arround the power steering pump and high pressure hose in the back of the engine compartment, I see a lot of Camry's leak I think it must be because of engine heat in the back area of the engine compartment.
It sounds like the power steering pump may not be generating enough pressure. To test the pump a high pressure gauge needs to be inserted in the line to verify pressure. If the pump fails it can send debris into the steering rack so you may want to get this looked at as soon as possible.
